During the course of a routine Starbucks run, it's not uncommon for the occasional misspelling to occur when a barista writes a customer's name on his or her cup (speaking from personal experience, my name is Maggie but I've received orders for "Megan," "Kristin," "Navy," and, inexplicably, "Maqéye"). However, for one St. Augustine, Florida, man, his grande white mocha came not only with a misnomer but with an insult: His cup was labeled "Diabetes Here I Come."

For reference, a grande white mocha latte made with 2 percent milk has 470 calories total, with 170 calories from fat—a number comparable to many of the coffee chain's flavored lattes and frappuccinos.

The customer, who chose to remain anonymous, told CBS syndicate Action News Jax that the label was particularly upsetting because two of his sisters suffer from type 1 diabetes. In response to the slight written on his cup, the customer penned his own message to the baristas of his local Starbucks: "2 of my sisters are diabetic, so...not funny."

The customer said he does not want an apology but rather wants to be certain that no future customers will be similarly ridiculed for their patronage. A representative from Starbucks corporate headquarters told Action News Jax that this type of behavior is not condoned by the retailer, and they are working to correct the situation. “We strive to provide an inclusive and positive experience for our customers, and we're disappointed to learn of this incident," they said. "We are working directly with the customer to apologize for his experience, and with our partners (employees) to ensure this does not happen again.”
